Results of the summarizing process for the arXiv paper: 2006.02775v1

In their paper titled "Design and Hardware Implementation of a Separable Image Steganographic Scheme Using Public-key Cryptosystem," Salah Harb, M. Omair Ahmad, and M. N. S Swamy propose an efficient hardware implementation of a steganographic cryptosystem based on public-key cryptography. The authors utilize digital images as carriers of secret data between sender and receiver parties in the communication channel. The proposed public-key cryptosystem offers a separable framework that allows for the independent embedding or extraction of secret data and encryption or decryption of the carrier using the public-private key pair. To encrypt and decrypt pixels of the digital image, they adopt the Paillier cryptographic system and design an efficient parallel Montgomery exponentiation core to perform underlying field operations in this cryptosystem. The hardware implementation results demonstrate efficiency in terms of area (resources), performance (speed), and power consumption. This small footprint makes it well-suited for embedded systems such as medical scanning devices, autopilot cars, and drones that require real-time processing engines to protect sensitive information during communication over unsecured channels. This paper provides valuable insights into designing efficient hardware implementations for steganography-based security systems.

In their paper titled "Design and Hardware Implementation of a Separable Image Steganographic Scheme Using Public-key Cryptosystem," Salah Harb, M. Omair Ahmad, and M. N. S Swamy propose an efficient hardware implementation of a steganographic cryptosystem based on public-key cryptography.

Background

Steganography is the art or practice of concealing messages or information within other nonsecret text or data in order to hide its existence from unauthorized viewers. It is often used by organizations to protect confidential information from being accessed by malicious actors while also providing authentication capabilities for legitimate users who are authorized to access the hidden message or data. In this paper, the authors propose a separable image steganographic scheme using public-key cryptography which allows for independent embedding/extraction of secret data as well as encryption/decryption of the carrier using public-private key pairs.

Proposed System

The proposed system utilizes digital images as carriers for secret data between sender and receiver parties in the communication channel. To encrypt and decrypt pixels of the digital image, they adopt the Paillier cryptographic system which uses two large prime numbers p1 and p2 along with an integer n = p1*p2 (where gcd(n) = 1). The encryption process involves multiplying each pixel value with n^r modulo n^2 where r is randomly chosen number between 0 < r < n^2 - 1 . For decryption process , it requires calculating inverse modular exponentiation operation i.e., (ciphertext) ^ (-lambda) modulo n^2 where lambda is calculated using extended Euclidean algorithm (EEA). Furthermore , they design an efficient parallel Montgomery exponentiation core to perform underlying field operations in this cryptosystem which helps reduce area , power consumption & improve performance significantly .

Hardware Implementation Results

The authors implemented their proposed system on Xilinx Virtex 5 FPGA platform using Verilog HDL language & compared it with existing software based implementation . They observed significant improvement in terms of area (resources), performance (speed), & power consumption due to their optimized architecture design . Their results demonstrate that their small footprint makes it well suited for embedded systems such as medical scanning devices , autopilot cars & drones etc .

Conclusion

This research paper provides valuable insights into designing efficient hardware implementations for steganography based security systems utilizing digital images as carriers for secret data between sender & receiver parties over unsecured channels . The proposed public key cryptosystem offers a separable framework that allows independent embedding/extraction of secret data & encryption/decryption operations using public private key pair efficiently without compromising on performance , area resources & power consumption making it suitable even for resource constrained embedded applications like medical scanning devices , autopilot cars etc .
